Florida's top prosecutor pounced on a planned ad blitz funded by Michael Bloomberg that defends "heavy-handed" clean air rules – slamming the former New York mayor as a "billionaire bully."

In a statement Friday, Florida's Attorney General Pam Bondi says the Environmental Protection Agency's Clean Power Plan will "drastically increase" power bills in the state.

"Florida has a great and conscientious track record of improving its air quality and protecting its environment," Bondi argues.

"Now a billionaire bully is attacking Florida, and 26 other states, for having the audacity of defending their citizens against the EPA’s heavy-handed and unlawful regulations, which will drastically increase Floridians power bills — something this billionaire clearly cares little about."

"This bully wants to defend the federal government; we want to protect the people we serve," she adds.

Bloomberg is reportedly bankrolling ads that target Bondi, and Attorneys General Chris Koster of Missouri, Bill Schuette of Michigan and Brad Schimel of Wisconsin.

"These four attorneys general are trying to stop the president from doing something that I think is terribly important," Bloomberg tells the New York Times.

"I want the public to know what they're doing. It's very bad for everybody."

According to Florida Politics, Bondi said in August she'd sue over the rules governing the carbon emissions during startup, shutdown and malfunctioning of power plants, arguing the regulations overstep the federal government's authority.

She contends the Clean Air Act gives the federal government authority to set standards regarding harmful pollutants, but it remains the states' responsibility to determine how to implement those standards.

"We will not step aside while the EPA, through heavy-handed federal overreach, threatens to upend a system that the EPA has approved multiple times and has provided a consistent, reliable framework to safely provide electricity to millions of Floridians across the state," Bondi said at the time, Florida Politics reports.

Independence USA PAC, Bloomberg's political action committee, says it will be airing the ads beginning this weekend.
